List and description of variables for steam?

Reddit Linux_Gaming - 24. Dezember 2025 - 20:42

Is there a list of variables with descriptions? I’ve found a few short ones here and there but I’d like something where I can get more information on when and how to use them.

EDIT: I generally only use steam to play games atm.

Team Fortress 2 runs worse on Fedora KDE over KDE neon. Possibly because of older Mesa stack on neon = better old game support?

Reddit Linux_Gaming - 24. Dezember 2025 - 20:25

Hello,

I was running KDE neon for about a year and decided to switch distros to Fedora 43 KDE.

It works great and has been very good, but TF2 specifically runs visibly worse especially when looking at a lot of geometry (actual model count doesn't seem to matter — I can be in intense team fights with about the typical performance — the problem is worst when looking at a large open-ended map).

My specs should have TF2 running at >200 FPS at all times, which is what it did on KDE neon, especially on older maps. I'm on the Wayland compositor now and was on the Wayland compositor on neon, so it can't be a X11/Wayland issue.

My Vulkan instance version is 1.4.328, and Mesa version is 25.2.7.

I've been running TF2 at lower settings than I typically did on KDE neon and performance is still worse at these high-geometry moments. There are moments in-game where I vividly recall a specific place I'm walking into/out of having much higher FPS on the same hardware stack and here running at a lower FPS. The "high-geometry" thing could also be a red herring, I'm not sure.

Is there something wrong with my driver stack? Vulkan version? Mesa/OpenGL version? Other problems I'm not seeing?

If there is any information at all I can give additionally that will help you good folks figure out the problem, I'm happy to give it.

Thank you.

EDIT: My specs:

16 GB DDR4 3000MHz RAM

AMD Ryzen 5 3600 6-Core Processor with 4.6 GHz max clock

Radeon RX 56 Vega Graphics

Kernel version: 6.18.2 tkg

Is SSD a must especially for modern games?

Reddit Linux_Gaming - 24. Dezember 2025 - 19:57

Title, basically i played Hogwarts Legacy notice some random framedrops maybe because of my HDD? The gpu or cpu and ram they are well above the recomended requirements, maybe they are waiting for hdd to give some data or assets maybe proton needs some overhead for data reads or any software tweaks i can maximize my hdd performance.

Context: didnt have any issues on windows using hdd and the game is rated platinum in protondb.

OS: Fedora 43 GNOME

I don't know how to use frame gen in games, can someone help me ?

Reddit Linux_Gaming - 24. Dezember 2025 - 19:56

I'm trying to play Ghost of Tsushima which has frame gen, GPU is rx 9060 XT, my monitor is 180 hz, OS is linux mint 22.2.

How do I like render lets say 90 fps and let the frame gen render/create the remaining 90 fps ?

I activated the frame gen option in the game but I don't even know if its working or how it works, this seems confusing to me.

Fix broken controller mappings on SDL2 2.30.0+

Reddit Linux_Gaming - 24. Dezember 2025 - 19:44

After SDL2 2.30.0 , controllers like Nacon GC100 are detected but buttons are swapped/missing in:

  • Heroic Games Launcher (Epic/GOG)
  • Ryujinx/Yuzu/Suyu Switch emulators
  • Any SDL2 app (non-Steam games)

Issue: Joystick backend refactor changed GUID/CRC detection. My Nacon GC100 worked perfectly before, now A=back button, etc

FIX:

Use the SDL_GAMECONTROLLERCONFIG environment variable with your controller's mapping string. Add it via Flatseal for Flatpak apps or prefix .desktop Exec lines with env SDL_GAMECONTROLLERCONFIG="your_string,"

I feel like every time I see someone complain about gaming on Linux, their always trying to play some AAA slop with kernel anti-cheat

Reddit Linux_Gaming - 24. Dezember 2025 - 19:16

Yes, your Activision-EA-Ubisoft-Epic Games sanctioned spyware may in fact not run the best on Linux, have you considered playing a game made by developers who don’t hate you?

issues with kisnt kn85

Reddit Linux_Gaming - 24. Dezember 2025 - 19:16

I am using a kisnt kn85 with kubuntu 25.10 (wayland).
I had issues with the `FN + Fxx` keys, untill i found this fix in this comment.

This fixed the issue when using the 2.4Gz mode (using their dongle). However i recently switched to cabled mode using the usb-C cable. This resulted in the same problem coming back (media keys don't work with FN, Only F key is registered).

Is there a config i could do with for instance something like keyd? or is there another fix?

Thank you :)

Proton and 2nd Hard/Solid-State Disk Drive Issues.

Reddit Linux_Gaming - 24. Dezember 2025 - 18:16

So I installed the greatest Total War game of all time (Shogun 2 by the way) on the most greatest Linux distro of all time (Mint by the way). Cool story right?

Well, whenever I install Shogun 2 on a drive that isn't the same as the one my main operating system and steam itself are located on, it no longer "just works." This is despite spending hours to ensure the 2nd drive is properly partitioned, formatted to ext4, let alone having steam actually recognize it as a mounted disk drive with a directory I've assigned that Steam can recognize and download/install games to.

My best guess is because Proton and Steam are located on the main drive my OS is on, Proton can't even see any game installed on the 2nd drive. I confirmed it with:

protontricks -l

The games installed on my 2nd drive don't even list whereas the ones on the main drive do when I run this command via terminal.

I'm curious if anyone else has had this problem and found a solution to get Proton to recognize and run games from any additional disk drives they may have.

Otherwise, Merry Christmas and Happy Holidays.

Debian full screen game issues

Reddit Linux_Gaming - 24. Dezember 2025 - 18:02

im running debian 13 gnome and am having a problem when running full sreen games, i have 3 moniters and if i launch the games with all moniters enabled the games will lantch but the mouse dose not line up with the buttons or the game resolotion is wrong or it detects the right resolotion but the game is distorted and squashed in the center of the screen, however if i disbale 2 moniters the game lunches fine, i am running a AMD GPU.

i have tried to lantch portal 2 and it sees the resolotion of 11520x2160 witch is the resolotion shown when i run xrandr under "screen 0" so i think the games are seeing that resolotion not the resolotion of my monitors.

any suggestions

Issues with AVMATRIX Driver on newer Kernels

Reddit Linux_Gaming - 24. Dezember 2025 - 17:29

Hey all,

I am a bit of a noob when it comes to troubleshooting on Linux. I have an AVMATRIX VC12 4K capture card and it has been working beautifully on Linux for months now using this driver. However, after kernel version 6.17.8 and any newer kernel version the driver will still run and I can pull audio using OBS, but the device no longer shows up as an option when trying to pull video from it in OBS.

I'm not necessarily needing someone to hold my hand, just looking for ways to troubleshoot this issue so I can assist with getting this driver working again.

Thanks!
